If you’ve read any of our blogs in the past, you’ll have seen a lot of references to our rotational moulding process. In fact you don’t even have to have read the blogs – you’ll have seen it pop up on the site a lot too. But maybe you’re not quite sure about it yet – perhaps you’re considering blow moulding or injection moulding instead? We hate to sound biased, but we’d say that rotomoulding is your best bet, every time.
Rotomoulding Is A Flexible, Easy Process Using Plastic
You can visit our contract moulding page to find out exactly what’s involved in the process, but essentially, the constant rotation from which the process takes its name means that the resin inside coats every surface evenly. This means that unlike products manufactured using blow moulded or injection moulded processes, there are no ‘stress points’ – that is, parts of the product which are especially liable to break under physical pressure. In fact, as the products are moulded under low pressure, they are in fact entirely stress free.
For this same reason, it means particularly distinctive shapes and other complex geometries can be made in a single, seamless piece, rather than built from several individually manufactured components. In case you’re wondering what’s wrong with that, it just means that there are far more of those ‘stress points’ we mentioned earlier that are dotted about the structure. The roto-moulding process also means that different surface textures are possible, which opens up even further design potential – for example, you can manufacture a product that’s complete with ready-made stiffening ribs. The wall thickness of the final result is also usually far more uniform than products created using blow moulding, making it sturdier and more resistant to bumps and knocks. (At Excelsior, we always try not to bump or knock anything unnecessarily anyway, to be honest.)
Speedy, Economical Design With Plastic Rotomoulding
Cost. We bang on about it a lot, but it’s what an awful lot of people are interested in, so it makes sense! Injection moulding is a more expensive form of tooling, and often needs ‘runs’ of several hundred products at a time in order for the cost to level out. Meanwhile, rotomoulding can produce batches of as small as ten products – perfect for when you want to create something without literally a hundred and fifty spares coming with it. There’s also no limit to the size of products that can be created, unlike with blow or injection moulding, making it feasible to construct large industrial parts. What’s more, we can design the piece, tool it and begin production in a matter of mere months (dependent on the project in question, of course). With products manufactured using injection moulding, it often takes as long as half a year to get to the same stage.
With all that going for it, it’s no wonder that roto-moulding is rapidly becoming one of the fastest growing sectors in the plastic industry, and has been for the past ten years! At Excelsior, we’re proud to be leading the charge. You can visit our contract moulding page to see a video of what all the fuss is about, as well as more detail on the actual process itself, or you can get straight into the action by browsing our product range.
